Dabbling and Diving Duck Research. The female has a dark brown head with some white around the bill, and a brown body. In breeding plumage the male has a black head with iridescent dark green, and a black breast.

Size: True to its name, the greater scaup is the larger bird at 18 to 20 inches in length, while lesser scaups are 16 to 18 inches long.While size can be challenging to judge in the field, this can be a useful comparison in a mixed scaup flock or when comparing to other duck species where the sizes are known.
